it's sorta like how a lot of ADHD people get tired when they take stimulants, my brain is just constantly seeking a ton of stimulation and if i don't satisfy that then i'm distracted by every little thing around me AND bored out of my mind.

you can think of it sorta like how a baby will keep grasping at things and being a menace, but then you put a toy in its hands and instantly it's utterly enamored and gurgling in joy.
